Description

Technical Field

[0001] This utility model relates to the field of automatic gluing technology, specifically an automatic gluing machine for racket rubber strips. Background Technology

[0002] Rubber strips increase the friction on the racket surface, allowing for better control of the ball's direction and spin during a shot. This helps athletes execute more precise technical movements and also protects the racket surface from scratches, wear, and other damage to some extent, extending the racket's lifespan. Therefore, they are widely used in the racket manufacturing process. An automatic gluing machine for racket rubber strips refers to an automated device specifically designed to automatically and evenly apply glue to the sponge layer of the racket rubber. Through a fixed fixture and an automatically moving glue applicator, the glue is automatically applied, ensuring that the rubber strip is firmly bonded to the racket and that it can be used normally. However, after the rubber strip is applied using an existing automatic gluing machine, it still needs to be removed manually. However, when removing the rubber strip manually, inconsistent force, angle, and speed can cause the rubber surface to be pressed by fingers, resulting in contamination or indentations, and pulling can cause the rubber strip to deform, stretch, or wrinkle.

[0003] Therefore, an automatic gluing machine for racket rubber strips is proposed to solve the problems mentioned above. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figure 1 - Figure 9 An automatic gluing machine for racket rubber strips in this embodiment includes a protective cover 3. A motor 15 is fixedly installed on the outer surface of the protective cover 3. A threaded rod 10 is installed inside the protective cover 3 and is rotatably connected to the output end of the motor 15. The threads on the surface of the threaded rod 10 are arranged in segments and symmetrically. Fixing rings 13 are sleeved on the outer surfaces of both ends. The threaded part of the threaded rod 10 is sleeved with a threaded clamp 9 in two as a group. The gripper 9 is a set or more. The gripper 9 has an opening in the middle and an inclined groove 36 at the lower end. The groove 36 is provided with a lower support plate 16. A motor 20 is fixedly installed at the corner of the outer surface of the gripper 9 near the lower end. The lower support plate 16 is fixedly connected to the output end of the motor 20. The lower support plate 16 is rotatably connected to the groove 36. An electric telescopic rod 14 is fixedly installed on the lower surface of the fixing ring 13. A fixing plate 11 is fixedly connected to the output end of the electric telescopic rod 14. The fixing plate 11 passes through the opening in the middle of the gripper 9. Among them, motor 15 and motor 20 are electrically connected to external control equipment. Each set of grippers 9 has a longer vertical plane portion facing each other. The length of the lower support plate 16 is no more than half the width of the rubber strip. The angle between the inclined surface of the groove 2 36 and the two side surfaces is equal. After the adhesive strip is applied, motor 15 drives threaded rod 10, causing each set of grippers 9 to move closer together and clamp both sides of the adhesive strip. When one end of the adhesive strip leaves the working area, electric telescopic rod 14 drives fixed plate 11 to descend and gradually approach the upper surface of the adhesive strip. Motor 20 drives lower support plate 16 to rotate to the bottom of the adhesive strip, where it works with fixed plate 11 to secure it, thus completing the overall securing of the adhesive strip around its perimeter. This allows the strip to be removed without manual intervention, avoiding the situation where inconsistent force, angle, and speed when manually removing the adhesive strip can cause contamination or indentations due to fingers pressing on the adhesive surface.

[0018] Below the protective cover 3, there is a workbench 1. On the upper surface of the workbench 1, there is a support platform 6, a bracket 7 and a support block 28. On the side surface of the workbench 1, there is a bracket 4. On the side surface of the bracket 4, there is one or more motors 34. A threaded rod 5 is provided between the bracket 4 and the bracket 7. The threaded rod 5 is fixedly connected to the output end of the motor 34. The threaded rod 5 is rotatably connected to the bracket 7. A threaded moving rod 35 is sleeved on the outer surface of the threaded rod 5. An electric telescopic rod 33 is fixedly provided on the lower surface of the moving rod 35. The output end of the electric telescopic rod 33 is fixedly connected to the upper surface of the protective cover 3. Among them, motor 5 34 is electrically connected to external control equipment. When the gripper 9 clamps the two sides of the rubber strip, the electric telescopic rod 33 retracts, driving the protective cover 3 and one end of the rubber strip clamped by the gripper 9 to lift upward, which facilitates the rotation of the lower support plate 16. When the rubber strip is fixed around the perimeter, motor 5 34 drives the threaded rod 5, thereby driving the moving rod 35 and the protective cover 3 and the rubber strip below it to move together, so that the rubber strip can quickly leave the working area, which is convenient for subsequent production.

[0019] A finished product placement platform 17 is fixedly installed on the upper surface of the support block 28. The finished product placement platform 17 is a curved surface with uniform undulation. Among them, the curved surface of the finished product placement platform 17 is consistent with the direction of the threaded rod 5, which allows the rubber strip to provide more uniform support when supported on the curved surface, effectively preventing deformation, indentation or edge wear of the rubber strip due to its own weight, and maintaining the appearance quality and performance of the finished product.

[0020] Support plates 31 are fixedly installed on both sides of the workbench 1. Near the upper end of the support plates 31, there are four enclosure plates 21. The enclosure plates 21 do not contact each other and are perpendicular to each other between any two adjacent enclosure plates 21. A baffle 2 32 is fixedly installed on the inner surface of the enclosure 21. A motor 4 29 is fixedly installed on one end of the baffle 2 32 near the enclosure 21. A threaded rod 4 25 is installed on the other side of the baffle 2 32. The threaded rod 4 25 is fixedly connected to the output end of the motor 4 29. A threaded moving platform 1 2 is threadedly fitted on the outer surface of the threaded rod 4 25. An electric telescopic rod 2 26 is fixedly installed on the upper inner surface of the moving platform 1 2. A support platform 27 is fixedly installed at the output end of the electric telescopic rod 26. A glue clamp 8 is fixedly installed on the side of the support platform 27 away from the enclosure 21. Among them, motor 429 is electrically connected to external control equipment. When the adhesive strip is placed in the working area, motor 429 drives threaded rod 425, so that moving table 12 can move in a straight line along the threaded rod 425. Electric telescopic rod 26 drives support table 227 and the dispensing fixture 8 fixedly installed on its outer surface to move up and down. In this way, they work together to complete the movement of dispensing fixture 8 in the horizontal and vertical directions, so that the equipment can apply adhesive strip with consistent force and speed, ensuring the consistency of the finished product.

[0021] The bottom of the support platform 16 is hollow. A baffle 122 is fixedly installed on the upper surface of the worktable 1. A motor 34 is fixedly installed on one side of the surface of the baffle 122. A threaded rod 33 is installed on the opposite side of the baffle 122. The threaded rod 33 is fixedly connected to the output end of the motor 34. A movable platform 20 with a threaded connection is threadedly sleeved on the outer surface of the threaded rod 33. The baffle 122, the threaded rod 33 and the motor 34 are all located in the hollow area below the support platform 16. A rubber strip placement platform 18 is fixedly installed on the upper surface of the movable platform 230. Among them, motor 3 24 is electrically connected to external control equipment. When a strip of glue is handed over, motor 3 24 drives threaded rod 3 23, which drives moving table 2 30 and the glue strip placement table 18 fixedly installed on its upper surface to move in a straight line. This allows the un-glued glue strip to be re-aligned with the glue outlet, which facilitates continuous glue application and improves the overall production efficiency of the equipment.

[0022] The outer surface of the threaded rod 10 near both ends is provided with a groove 12, and the fixing ring 13 is fitted into the groove 12. The groove 12 and the fixing ring 13 have the same width. The inner surface diameter of the fixing ring 13 is the same as that of the groove 12. The annular part of the fixing ring 13 is larger than a semicircle. When the fixing ring 13 is fitted onto the outer surface of the groove 12, the groove 12 can effectively limit the fixing ring 13, so that it will not shake or shift unnecessarily during use, thus ensuring the overall stability of the equipment.

[0023] The working principle of the above embodiments is as follows: During use, motors 15, 20, 34, and 49 are all electrically connected to external control equipment. Motor 15 drives threaded rod 20, causing each set of grippers 9 to move closer together and clamp the two sides of the adhesive strip. Electric telescopic rod 33 retracts, lifting the protective cover 3 and one end of the adhesive strip clamped by the grippers 9 upwards. Electric telescopic rod 14 drives the fixing plate 11, causing it to descend and gradually approach the upper surface of the adhesive strip. Motor 20 drives the lower support plate 16, causing it to rotate to the bottom of the adhesive strip and cooperate with the fixing plate 11 to tighten it, completing the comprehensive tightening of the adhesive strip around its perimeter. Motor 5 drives threaded rod 5, causing the moving rod 35 and the protective cover 3 and adhesive strip below it to move together, allowing the adhesive strip to quickly detach from the adhesive strip placement table 18 and be repositioned on the finished product placement table 17. This allows for detachment without manual intervention, avoiding contamination or indentations caused by fingers pressing on the adhesive surface due to inconsistent force, angle, and speed when manually removing the adhesive strip.

[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
